Wilmington / Greenwood
Greenwood has 1,564 residents (give or take 326) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US1031560, checked 2026-10-19), about 1,970 people per square mile.
Greenwood is about 64 miles from the Census center point for Wilmington in a straight line and covers 0.794 square miles of land (Census 2024 Gazetteer internal points and land area, https://www2.census.gov/geo/docs/maps-data/data/gazetteer/2024_Gazetteer/, checked 2026-10-19).
Of the 648 occupied homes in Greenwood, 5% heat with natural gas, 11% with heating oil, 76% with electricity and 8% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US1031560, checked 2026-10-19).
Electricity already heats 76% of Greenwood homes, ahead of oil at 11%, and a home on electric baseboard sees the biggest bill change from a heat pump because it replaces resistance heat one for one.
Greenwood has 4 points more oil heat than Sussex County as a whole, where 7% of homes burn oil, and 23 points more electric heat than the county's 53% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US10005, checked 2026-10-19).
Greenwood has 690 housing units, 18% built before 1940 and 49% before 1980, with 27% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US1031560, checked 2026-10-19).
Greenwood has 14 points more pre-1940 homes than Sussex County as a whole (4%) and 22 points fewer homes built after 2000 than the county's 49% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US10005, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Greenwood home was built in 1985 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US1031560, checked 2026-10-19) and the median home has 5.6 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US1031560, checked 2026-10-19).
52% of Greenwood homes are single-family detached, 16% are in two- to four-unit buildings and 21% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US1031560, checked 2026-10-19).
56% of Greenwood homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US1031560, checked 2026-10-19), so beside the 52% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Greenwood has 13 points fewer detached houses than Sussex County overall (65%) and 12 points more five-plus-unit buildings than the county's 9% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US10005, checked 2026-10-19).
56% of Greenwood homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US1031560, checked 2026-10-19), so the market splits between resident-led jobs where the occupant picks the system and landlord-led jobs where they do not, and the rebate paperwork differs.
No electric utility is on file for Greenwood on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Median household income in Greenwood is $73,345 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US1031560, checked 2026-10-19); many state and utility heat pump rebate programs set higher incentive tiers for income-qualifying households, so the household income on the application, not the town median, decides which level applies.
Heating design temperature: 18F.

That 18F figure is the Sussex County cold-day number a Greenwood heat pump is sized against, so ask the installer to show the system's heating output at 18F, not at the milder rating-label temperature.
Ask for the heat-loss calculation room by room; the median Greenwood home has 5.6 rooms and was built around 1985, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
